Websites often put copyright information in the footer to let the public know the site is copyrighted. The copyright notice also tells site visitors who owns the website, though it sometimes also includes information about the company that developed the site or the template the site owner used.
You can add the copyright notice to your WordPress footer by editing “footer.php” and placing the text within the tags that structure the footer. Give the footer a class name so you can style it in Cascading Style Sheets (CSS) code later.
